CUDA kernel messages

hello there, im very new and have only just managed to compile my first fortran program using an accelorator. however, when i run it i get messages to the screen every time a kernel is executed and i cant seem to turn them off - any ideas?

Ive tried setting a range of environment variables to -1 (off i assume) to no avail so far

Hi Mike,

You most likely have “ACC_NOTIFY” set which shows every time a kernel is launched. To disable, either unset the environment variable or set it to zero. Zero is ‘off’, all other values are ‘on’.

Hope this helps,

Top shout Mat - worked a treat now I know 0 is off and all others are on!
